Company patents

DAIFUKU CO., LTD.

DAIFUKU CO., LTD. maintains a strong focus on its core 'Conveying & Handling' technology, representing 63.7% of its portfolio, yet surprisingly, its 'Semiconductor Manufacturing Process' category saw an explosive 320.0% YoY growth in 2024, indicating a significant emerging focus in this specialized area, despite a subsequent decline of 14.3% in 2025 and a partial year decline of 77.8% so far in 2026. While core areas like 'Conveying & Handling' and 'Industrial & Autonomous Control' show some year-over-year fluctuations, the company's patent strategy appears to be diversifying into high-growth, specialized manufacturing processes.
